Before beginning the official test, Kenne Bell tech tapped the 5.4-liter with all manner of data-logging equipment. Unless the KB differs significantly from the Lysholm, this suggests that the same size TVS will outperform the KB all day. Anonymous. 2,500 472.68 225.00 524.35 249.60 51.67 24.60 652.51 310.60 128.16 61.00 The peak power jumped from 518 rwhp with the M122 to an impressive 609 with the TVS. Rev 300 Tvs Lotus Supercharger. VMP 11-14 Mustang 5.0 L Supercharger Kit - Odin 2.65L TVS - Complete See more. "Stock" M90 look, but much more power. If you want to lose the warranty and add the Kenne Bell, that program will squeeze your wallet for $31,995. Roots blowers tend to be only 40–50% efficient at high boost levels; by contrast, centrifugal (dynamic) superchargers are 70–85% efficient at high boost. (see Twin Screw vs. Roots types are simple pumps, moving air from above to below. The ZR1 is supposed to have 133HP more than the Z06 (638 vs 505), but I … At this same intersection of PR and flow, the same size TVS also needs 8,000 RPM but is at 68%. Unfortunately for enthusiasts, positive-displacement superchargers are ultra-sensitive to inlet restrictions. Not so many moons ago, I was responsible for one of many supercharger comparison tests (in another magazine), putting an Eaton Roots supercharger against its positive-displacement cousin, the Twin Screw, and here I am again. One of the problems associated with comparing any two performance components, let alone superchargers, is how to accurately test them. Centrifugal Supercharger. There is talk amoung Roush insiders/owners right now about a kit that Roush may have worked on that replaces the roots style rotors in the M90 on the 4.6L supercharger with the more efficient TVS rotors (half way between roots and twin screw). Download Image. May 11, 2019 May 11, 2019 Constance Fisher Constance Fisher 0 Comments. Horse Sense: If you have a GT500 and want it to undergo a Super Snake conversion, the base package with the TVS blower and all the other mods that make it a 600hp Super Snake will set you back $27,995. The corrected result is even more surprising (to me) than my initial analysis: The TVS is far more efficient vs. this particular twin-screw than I initially thought, as you stated above. Is the restriction in the intake manifold between the rotors and the throttle body, the throttle body, the mass air, the inlet tube, or the filter? TVS vs. Twin-screw. Our data logging included the air/fuel ratio, ambient air temperature, engine speed, boost pressure before and after the intercooler, inlet air temperature before and after the intercooler, water temperature through the intercooler core, mass air voltage, timing curve, and even inlet vacuum before the supercharger. That is not a poll option. 3,500 513.35 342.10 585.25 390.02 71.90 47.92 701.07 467.20 115.82 77.18 With both systems available for the Super Snake and as upgrades for the standard GT500, it was only natural that we take a long, hard look at the performance offered by each. In anticipation of the high-boost runs, the fuel tank was filled with 100-octane race unleaded fuel to eliminate any possibility of detonation. In stock configuration, the M122 blower provided a peak of 8.7 pounds of boost, but for our needs, we wanted to find out what was possible by running the smallest blower pulley possible. Historically as we all know the twin screw comes strong in the upper RPM range, I'm hoping it narrows the margin in the lower. It has been well documented in numerous tests by automotive engineers around the world that the Twin Screw concept is, unquestionably, more efficient (cooler air charge temperature and lower parasitic loss). The 8 Bays of the Thunderbolt TVS-872XT each have their own dedicated LED indicator, as well as their own locking mechanism to ensure drives are not accidentally removed whilst in use, an annoyingly common way that people screw up there RAID array – you would be amazed! Whipple’s positive-displacement twin-screw compressor delivers massive power across entire RPM range. Equipped with the factory M122, 2.59-inch blower pulley and optimized tune (11.5 A/F and 23 degrees timing), the 5.4 produced 518 hp (up from 443 hp in stock configuration). The screw blower is so efficient it doesn’t need all the extra cubic-inches to create the horsepower like a big cubic-inch nitrous or turbo motor does.“ Both roots and screw blowers are great ways to make big power in any class of racing, and they’re perhaps the most tried-and … Either way, at JB we’ve got a heap of different options including: LED TVs. Shelby offers the Kenne Bell blower package as its most powerful Super Snake option. Whipple Superchargers twin screw design makes them the most efficient supercharger available for making horsepower. Historically as we all know the twin screw comes strong in the upper RPM range, I'm hoping it narrows the margin in the lower. Either one has the capability to provide more power than your average driver is really equipped to handle, but for those who find too much is just right, now you’re better educated as to how these two options compare. Light-emitting diodes result in a higher refresh rate, more contrast and brighter colours. Even the test vehicle (originally an ’00 Saleen equipped with a Two-Valve 4.6) has been upgraded to none other than the mighty Shelby GT500. Stage 3 745 0 2.8 Mammoth Kenne Bell Kenne Bell Kenne Bell Kenne Bell "Stock" M90 look, but much more power. The rotors on this system literally look like screws. The final test was to remove the TVS and install the Kenne Bell Twin Screw supercharger. Back in the days of Kenne Bell twin-screw 2.8 vs Magnuson 2.3 TVS, the real difference was that the TVS was better efficient to 16psi, and then the larger size of the Twin-Screw helped outflow at anything above that. These power gains came with no change in air/fuel, timing or blower pulley size. The front drive / front inlet design allows for a shorter less restrictive intake path allowing for improved air flow and superior performance. It should also be noted that the 5.4 was equipped with a standard 17V Boost-a-Pump, stock 52-lb/hr injectors, and a custom tune to maximize power production with an air/fuel ratio of 11.5:1 and 23 degrees of total timing (values used for all of the tests to ensure repeatability). Naturally, backup runs were recorded to verify the power numbers generated by each pulley size. Oftentimes it’s difficult enough to get a normally aspirated motor to cooperate and produce repeatable results on a dyno, let alone some supercharged mod-motor monstrosity. By comparison, the Kenne Bell required only 12,700 rpm to produce the same 20 psi. But Its not likely relevant for the street. But a twin-screw supercharger compresses the air inside the rotor housing. Now shipping all Gen 3, Gen 4 and Gen 5 systems. Like the Roots supercharger, the air inside a twin-screw supercharger is trapped in pockets created by the rotor lobes. Screw) superchargers work by pushing air through a pair of interlocking rotors as the assembly rotates. While the TVS is certainly a big step up from the standard M122 supercharger, Shelby knew that many Super Snake owners were going to want even more. From a reader’s standpoint, I’m sure you were mostly concerned with how much power each system made, but there was–and still is–much more to the equation than sheer power number. The overall performance is enhanced, and you feel like you have a much larger cubic-inch engine at any throttle input.” Not all Whipple units look the same, either. Running the stock ind-uction system from the blower manifold forward resulted in a peak power number of 664 hp. Taking these same readings between the throttle body and mass air or between the mass air and filter will help you know exactly where the restriction is most prominent. More times than not, members post up that what they purchased is the best but never experienced others. Lv 6. TEST HP VAC SC MANIFOLD TB INLET MASS AIR FILTER With an increase in both displacement (2.3 versus 2.1 liters) and efficiency (see previous description of changes to TVS), it’s not surprising that the TVS blower increased the power output of the GT500 motor. Page 1 of 2. Torque production exceeded 700 lb-ft from 3400 to 5700 rpm. All of these things must be accounted for in order to produce reliable results. The more things change, the more they stay the same. First, the originals with CFM conversions...then an overlay. By running the same 2.59-inch blower pulley on the TVS blower, the peak boost numbers jumped from 11.5 to 14.5 psi. We’ve seen TVS GT500s, such as Justin Starkey’s (of VMP Tuning), make nearly 700 rwhp so optimized. This meant the installation of a 2.59-inch blower pulley (using a smaller pulley requires machining of the b. To satisfy owners with a serious thirst for power, Shelby decided to make its Super Snake available with the Twin Screw design from Kenne Bell. It is also powered by a belt driven from the engine crankshaft. If you're looking to make big power in your high-performance vehicle, the TVS 2650 is what you need. Were maximum power the design goal, you’d quickly see a change to the Twin Screw design. 4,500 504.30 432.10 587.17 503.10 82.87 71.00 725.24 621.40 138.07 118.30 A twin-screw supercharger operates by pulling air through a pair of meshing lobes that resemble a set of worm gears. Thats what we call a blower upgrade. Understanding how many owners of both solutions (TVS and Twin Screw) made the switch in the other direction should be solid information that can be considered valuable when making a supercharger purchasing decision. “The symmetrical rotor design of TVS technology allows for a much higher RPM ceiling. To say that a Twin Screw supercharger is more efficient than a Roots supercharger is hardly news. Like the Roots supercharger, the air inside a twin-screw supercharger is trapped in pockets created by the rotor lobes. Save up to $1,000 with Re-Tune. The TVS™ supercharger’s patented design features twin four-lobe rotors with 160-degree twists and high-flow inlet and outlet ports that greatly enhance thermal efficiency, deliver higher volumetric capacity and enable higher operating speeds. As with the M122, there was likely more power to be had with changes to the air intake and possibly a larger crank pulley. Twin-Screw supercharger. Is it really necessary to upgrade a supercharged motor with another supercharger? Equipped with the same blower pulley, the TVS supercharger increased the peak boost pressure from 11.5 psi with the M122 to 14.5 psi. 1 of 15. Twin-screw melt granulation offers the benefits of continuous manufacturing — providing a reduced footprint and improved economics — but with a greater degree of process control, with consistent product quality achieved through the implementation of different process analytical technologies (PATs). 1 decade ago. Today, the preferred choice is the Twin Screw. You've come to the right place, Hemituner Performance offers many different superchargers for this platform, and have the knowledge to help take your 6.4L powered HEMI to the next level. There are good reasons why OEM manufacturers rely on Twin Vortices Series (TVS) technology for factory supercharger applications: higher performance with ultimate reliability. include; Turbo mustang drag car gear; Supercharger Tech The Kenne Bell 30HP Advantage $600 "Real" Cool Air Kit is standard on Kenne Bell Kits. For a mainly street-driven car within the positive-displacement family, we like either a twin-screw or an Eaton TVS supercharger. Despite the same blower pulley size, the Kenne Bell offered 23 psi of boost and 736 lb-ft of torque. It’s hard not to be impressed by the power potential of the GT500’s 5.4-liter engine. 2 Answers. 6.4 Hemi Supercharger Kits Are you in the market for a 6.4L HEMI supercharger? Contents. As with the twin-screw design, the TVS supercharger was developed to expand the efficiency range of the supercharger to deliver more power at lower RPM and sustained boost at higher RPM, while requiring less engine power to drive. Available in some of the world's most powerful production cars and as an aftermarket upgrade, it is the perfect choice when you need to flow massive amounts of air. Not because of better or worse performance, but because of. By comparison, the original Eaton supercharger rotating assembly featured three lobes twisted 60-degrees. The cars were driven on the same track, by the same driver, on the same day. The SLP 1900 TVS supercharger is a positive displacement supercharger that features twin four-lobe rotors that are twisted 160-degrees. Personally, I would go with the Whipple Twin-Screw. Lysholm Twin-screw (a.k.a. Positive displacement pumps – such as the Roots, twin-screw (Lysholm), and TVS blowers. Articles by: GENERATIONS. The most powerful Twin Screw version from Kenne Bell is good for a solid 800 rwhp with no other changes to the stock 5.4 engine. At the end of the day, one can buy what they "want" or buy what they "need". LCD TVs. One of the often-overlooked aspects of any supercharged engine is its induction system. Every SAE paper ever written confirms this fact, and the real reason OEMs use the Roots blower is that it provides an excellent combination of power, reliability, and cost. In stock configuration, the M122 blower provided a peak of 8.7 pounds of boost, but for our needs, we wanted to find out what was possible by running the smallest blower pulley possible. A twin-screw supercharger operates by pulling air through a pair of meshing lobes that resemble a set of worm gears. The Eaton Twin Vortices Series (TVS) is an Eaton product, so basically all superchargers and kits are related in some way through the origin of the rotors. Since it was already installed on the motor, the first series of tests was run with the stock Eaton M122. While the previous test involved the smaller M90 Eaton and the 3150 Autorotor, this one involved much-improved versions of the original combatants. Since it was already installed on the motor, the first series of tests was run with the stock Eaton M122. 7 1. Five generations later, the TVS® (Twin Vortices Series®) was a revolutionary design that provides an incredible 12% efficiency improvement. The 5.4 looked like a cardiac patient with hordes of wires running out of every possible orifice. In the case of a supercharger, buy what you think will make you feel the best. Like the comparison between the M122 and the TVS, the Kenne Bell Twin Screw supercharger was both larger in displacement (meaning more output per revolution) and more efficient (meaning less charge temperature per pound of boost). The TVS™ supercharger is capable of running with a high thermal efficiency (up to 76 percent) across a wider operating range. This means it took 147 hp to drive the TVS supercharger at this speed and flow level. And when compared with previous three-rotor designs, the TVS represents a night-and-day difference in overall performance. Lysholm Twin-screw (a.k.a. These numbers are the rated flywheel power outputs just as the stock GT500 is rated by Ford at 500 flywheel horsepower. The combination of the performance tune and swapping on the 2.59 blower pulley brought the peak power output from 443 to 518 hp. REV 300 supercharger kit based on a Eaton Harrop TVS1320 twin vortices compressor, a water to air chargecooler can be sandwiched in, fits Elise body. [Main content. Case in point, that positive-displacement supercharger slugfest pitted the like-displacement 3150 Twin Screw Autorotor versus the standard Roots-style M90 Eaton. Some TVs may be better for sport watchers, and other TVs may suit those who prefer movie or series. Replacing the mass air housing and filter (Stage 2 upgrade) dropped the vacuum present in the inlet tract from 5.3 inches down to 3.3 inches and increased the peak power to 727 hp. 4,000 512.72 390.50 587.30 447.30 74.58 56.80 718.99 547.60 131.69 {{{100}}}.30 Replacing the throttle body, inlet air tube, mass-air housing, and filter assembly improved the power output of the supercharged 5.4 from 664 hp to 745 hp. Driveability, bang for the buck, dependability. Starting out where the TVS Roots blower left off, the 2.8-liter H-series blower from Kenne Bell is capable of supporting more than 1,000 flywheel horsepower and has already demonstrated that it’s capable of producing 800 rwhp on an otherwise stock GT500 engine. While the power numbers alone confirm the blower hierarchy, here’s additional information provided by another form of dyno testing: namely, a blower dyno. It should be said that additional power is available from the stock M122 blower with a larger crank pulley and modifications to the intake tract (air filter and inlet tubing, mass air housing, and throttle body), but ultimately, it’s the blower itself that limits power production. The answer is easy: anyone who pulls up next to a car sporting 790 rwhp! “It’s a difficult area to measure, meaning the useful RPM range of normal driving – but a twin-screw supercharger tremendously increases performance in those areas, separate from even wide-open throttle. Just think, you could be stuck with just 664 hp running the same pulley configuration or making as much as 774 wheel hp (800 with H-series blower). Kenne Bell even offers a larger mass air housing and filter assembly. TVS 1900 Performance Chart [2] Eaton FAQ [3] - scroll down to 3rd Q from bottom Hope this makes some feel a little better. (You must log in or sign up to reply here. Of course, we also had charge temperature measurements and even test results from Kenne Bell’s own blower dyno. 2,000 442.48 168.50 473.73 180.40 31.25 11. When boost is not called for they have virtually no parasitic losses and big advantage for OEM use. “The symmetrical rotor design of TVS technology allows for a much higher RPM ceiling. Available for most modern late model Ford, Chevy and Dodge applications. Why? In the case of the 5.4-liter GT500 motor, a simple vacuum gauge hooked up between the throttle body and supercharger will indicate whether vacuum is present. What is a blower dyno, you ask? A supercharger is an air compressor that increases the pressure or density of air supplied to an internal combustion engine.This gives each intake cycle of the engine more oxygen, letting it burn more fuel and do more work, thus increasing the power output.. Power for the supercharger can be provided mechanically by means of a belt, gear, shaft, or chain connected to the engine's crankshaft. Replacing the standard 2.8 blower with the 2.8 H-series took the 5.4 to 800 rwhp (using the same 2.5-inch blower pulley and Stage 3 induction). Equipped with the M122 supercharger, torque production exceeded 500 lb-ft from 3,000 to 4,700 rpm, with a peak of 514 lb-ft. The TVS does seem to have taken it to the twin screw guys recently. I … Along with the 1.9L TVS blower, the basic VMP kit also includes a high-flow inlet elbow with the proper vacuum line and PCV line fittings. The previous test, like most comparisons, was not without its difficulties. Roots and twin screw are both fixed displacement superchargers. These runs help eliminate anomalies that can occur during testing. VMP Gen3R TVS Upgrade Kit for 03-04 Cobra "Terminator" including VMP's Maximum Effort Options See more. The Eaton, on the other hand, simply moves air from one side of the blower to the other. Twin-screw superchargers don’t create anywhere near as much heat as a Roots-type blower so, while they can’t usually be used with intercoolers, they tend to require less cooling anyway. It also has a higher speed capability, from 18.000 to 24.000 rpm, which produces a broader map width. Every component in the induction system must be up to the task of supporting the desired power level. The Eaton TVS R2650 is the newest and largest TVS model. Its impressive performance is largely due to the unit’s state of the art rotor assembly. 3,000 501.39 286.40 565.46 {{{323}}}.90 64.07 37.50 672.43 384.10 106.97 60.20 I really think TRD hit it out of the park with this kit. The Eaton TVS R2650 is the newest and largest TVS model. Luckily for us enthusiasts, the gang at Kenne Bell has spent long hours on the dyno replete with data logging at each point to determine where the restrictions exist, and then to produce the necessary products to cure the situation. Screw) superchargers work by pushing air through a pair of interlocking rotors as the assembly rotates. No OEM uses a twin screw. 1 decade ago. Another advantage of roots types is that both rotors spin at the same rpm because both rotors have the same number of lobes -- typically 3, except TVS has 4 high … Though enthusiasts tend to lump the positive-displacement superchargers into one group, there’s a significant difference between the Twin Screw Kenne Bell and the Roots-type Eaton. Eaton Twin Vortices Series (TVS) technology opens up a new world of possibilities for products that require precision air flow solutions. How much do these restrictions hurt the power output? Before getting to the results, it’s worth recounting a bit of forced-induction theory. Thus the Twin Screw reduced the inlet charge temp, blower speed, and parasitic losses required to reach the desired boost level. Designed and manufactured by Harrop to OE standards, utilising the latest generation Eaton TVS supercharger technology, the TVS1320 Supercharger system is exclusively designed for the FA20 engine. Answer Save. The increase in boost pressure has a positive effect on the torque curve, elevating the peak torque output to nearly 600 lb-ft. Torque production exceeded 500 lb-ft from 2,200 rpm all the way to 6,300 rpm (our redline). In addition to the heat advantage from the better efficiencies, these maps … If any vacuum is present when running at or near the peak engine speed at wide-open throttle, there’s a restriction in the inlet system somewhere. It's tires, wheels, paint, curb feelers. In today’s video, we strap our 2012 Mustang GT500 to the dyno and put our VMP Gen3R head to head with a competitor’s 2.8 L twin-screw supercharger. 5,000 497. As expected of a positive-displacement supercharger, the torque curves were pretty flat. {{{80}}} 92.96 35.40 Of course, these swaps require proper air/fuel and timing values that are commensurate with the available fuel octane. The TVS, particularly the VMP GEN II, will make more torque...and hit much harder...than a small twin screw. I can't fathom anyone making that move. Edelbrock’s Eric Blakely adds, “The internal bypass allows the TVS blower to be ‘unloaded’ during constant manifold vacuum periods thereby creating less parasitic drag on the engine. Five generations later, the TVS® (Twin Vortices Series®) was a revolutionary design that provides an incredible 12% efficiency improvement. im sure he will help you with that! Any vacuum present in the inlet systems costs you power. Chevy does on theirs. No longer applied only as a supercharging device used to increase horsepower and torque, TVS technology has reached a transition point, evolving as a tool with a range of applications across various industries. The cars were driven on the same track, by the same driver, on the same day. Relevance. Since the stock blower will already deliver 550 rwhp with bolt-ons and tuning (up from roughly 440 rwhp in stock trim), the TVS looks pretty enticing, and it’s no wonder Shelby Automobiles chose to offer the TVS as on of the blower upgrades for its Super Snake program. The guys at Kenne Bell border on obsessive when it comes to information, and despite the time required, it’s hard to complain about it. The more options we have the merrier. The Eaton TVS Supercharger has been improving engine performance since 1985, beginning with the reknown M-Series. Tvs Vs Twin Screw. Compared to the more traditional M122 Roots supercharger, the new TVS offers a greater lobe count (four versus three), increased rotor twist (160 degrees versus 60 degrees), and revised inlet and discharge architecture, to say nothing of the increase in displacement (2.1 versus 2.3 liters). MENU. The largest blower tested, the Kenne Bell 2.8-liter H-series, produced the highest boost pressure. {{{90}}} 566.69 215. Share this photo. Who (you might ask) really needs 800 rwhp? With the testing completed on the M122, it was time for the Super Snake to receive the TVS blower upgrade. Caddy does on theres. 5,500 481.46 504.20 559.76 586.20 78.30 82.00 708.92 742.40 149.16 156.20 Basically, Eatons take on TVS vs. twin screw. The longer you’re on the throttle, and the longer it’s in boost, the higher the temperature will rise with a roots-style blower, so … For a mainly street-driven car within the positive-displacement family, we like either a twin-screw or an Eaton TVS supercharger. Historically, twin-screws had an efficiency edge but a few years ago the TVS -- now on the '13 GT500 (2.3L), ZR1 vette (2.3L) and ZL1 Camaro (1.9L) -- is both highly efficient and virtually no off-boost losses -- argueably the best of both worlds. VMP 105 MM THROTTLE BODY FOR 2020 GT500 Just as it sounds, the blower dyno is used to evaluate superchargers without regards to the engine. STOCK BLOWER TVS DIFFERENCE KENNE BELL DIFFERENCE ). Nowhere was this more evident than the use of the Twin Screw on the (cost-is-no-object and higher horsepower) Ford GT. The ZR1, because of the supercharger, did weigh 95 pounds more than the Z06 but it also had a bigger front splitter. It's a personalization of the car. Comparison Between Roots, Twin Screw and Centrifugal Supercharger in Tabular Form: S.no . Basically, it does the job of reaching the desired power level (usually not terribly high on a production vehicle) at an attainable cost and with quiet execution. Certainly it would be interesting to compare the Roots and the Twin Screw in the exact same displacement and with equivalent aero-restriction inlet systems to see the similarity of the numbers, but for now, Kenne Bell’s test provides an interesting look at two of the popular upgrade options for GT500 owners as available. Configured to produce 20 psi of boost (a level not attainable with the TVS on the 5.4), the TVS checked at 18,000 rpm, 340 degrees of discharge temperature, and a whopping 147 hp worth of parasitic drive loss. Plus, it's the same bolt on assembly that Ford uses. By contrast, a twin-screw blower can never truly be unloaded even with a bypass, because if it is spinning, it is compressing air whether it is needed or not. Run with the same blower pulley, timing, and air/fuel, the Super Snake pumped out nearly 790 rwhp, a gain of 175 hp more than the already powerful TVS and nearly 300 hp more than the stock M122.
